ObjectiveTo explore the expression of CD3+ CD8+ human leukocyte antigen (HLA)-A2+T lymphocytes with specificity to the different hepatitis B virus (HBV) peptides in the peripheral blood mononuclear cells (PBMC)from the patients with hepatitis B associated hepatocellular carcinoma (HCC).MethodsThe HLA-A2+ PBMC from four patients with hepatitis B associated HCC were incubated with five HBV/HLA-A2 pentamers respectively,which were HBV sAg (FLLTRILTI),HBV sAg (GLSPTVWLSV),HBV sAg (WLSLLVPFV),HBV core (FLPSDFFPSV),and HBV pol (FLLSLGIHL),as well as anti-CD3-pacific blue and anti-CD8-fluorescein isothiocyanate (FITC).Then,HBV/HLA-A2-CD3-CD8 positive cells were detected by flow cytometry. The monoclonal HBV/HLA-A2-CD3-CD8+ cells were acquired by fluorescenceactivated cell sorter,and cultured and identified by flow cytometry.The anti-HBV specific T lymphocytes were then cultured with HepG2 (HLA-A2+ ) cells and the release of interferon γ (IFN-γ)were determined by enzyme-linked immunosorbent assay (ELISA),Res(a)ltsThe percentage of antiHBV T lymphoeytes with specificity to GLSPTVWLSV in total CD8+ T lymphoeytes from four patients with hepatitis B associated HCC was 1.44％±0.04％,which was higher than those to other four HBV antigen peptides (0.68％±0.08％ of FLLTRILTI,1.06％±0.09％ of FLPSDFFPSV,0.56％ ±0.04％ of FLLSLGIHL,and 0.46％ ±0.08％ of WLSLLVPFV) (t=0.001,P＜0.05).The two lines of monoclonal cell with specificity to GLSPTVWLSV both exhibited high level of IFN-γ expression after incubated with hepatic carcinoma cell line HepG2 (HLA-A2+)with HBV GLSPTVWLSV peptide.ConclusionsCD3+ CD8+ HLA-A2+ cells with specificity to the different HBV peptides exist in PBMC of patients with hepatitis B associated HCC.The expression level depends on HBV antigen peptide sequences and genomic sites.

OBJECTIVETo investigate seminal parameters in noninflammatory chronic prostatitis/chronic pelvic pain syndrome (CAP III B).

METHODSA total of 74 consecutive cases of patients who had been diagnosed as CAP III B and 46 cases of controls were included in the study. Severity of symptoms in men with CAP III B was defined according to the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). All of them underwent a 'four glass-test' including leukocyte determination in expressed prostatic secretions (EPS), voided urine after prostatic massage (VB3) and ejaculate semen followed by analysis according to WHO. The analysis included seminal volume, pH, duration of liquefaction, sperm density, vitality, motility(a + b) and morphology. Correlations between the duration or the severity of symptoms and spermiogram results in patients with CAP III B were assessed respectively.

RESULTSThe CAP III B group and the control group differed significantly in ejaculate volume, duration of liquefaction and motility, while the remaining parameters did not differ significantly. The duration of chronic pelvic pain showed apparently positive correlationship with liquefaction time, while the symptom duration negatively correlated with sperm motility. The NIH-CPSI score had no significant relationship with seminal volume, duration of liquefaction and sperm motility.

CONCLUSIONOur results indicate that CAP III B can have a significant negative impact on sperm volume, liquefaction and motility. Our data also supports the results that the longer the duration of symptoms, the more influences on semen liquefaction and motility might be.

This study was aimed to investigate the changes of reactive oxygen species and antioxidative capacity on nitric oxide induced apoptosis in HL-60 cells. By means of in vitro incubation of HL-60 cells with sodium nitroprusside (SNP), the growth inhibition was detected by MTT assay. Cell morphology was observed by transmission electronmicroscopy and light microscopy. The apoptosis was analyzed by DNA agarose gel electrophoresis, DNA content and Annexin-V/PI labeling method. Reactive oxygen species (ROS) labeled with dihydrorhodamin 123 in cells was determinated by flow cytometry. The SNP-treated cells were examined for glutathione (GSH) level and activity of catalase (CAT), glutathione S-transferase (GST) and glutathione peroxidase (GPX). The results indicated that SNP could inhibit HL-60 cell growth. Cell apoposis was confirmed by typical cell morphology, DNA fragment, sub-G(1) phase and Annexin-V/PI labeling method. HL-60 cell apoptosis was induced by SNP in a dosage- and time-dependent manner. After exposing to SNP at the concentration of 0.5 - 3.0 mmol/L for 48 hours, the mean fluorescence intensity of ROS in cells was significantly higher than those in groups control and potassium ferricyanide (PFC). During the apoptosis process, level of ROS in cells increased, levels of GSH, CAT, GPTand GPX decreased. The significant dose-effect relationship existed between the levels of ROS, CAT, GST, GPX and SNP dose. It is concluded that change of intracellular reactive oxygen species and antioxidative capacity are an important factors during the process of SNP-induced apoptosis in HL-60 cell.

To study the molecular mechanisms of nitric oxide donor sodium nitroprusside (SNP) -induced apoptosis in K562 human leukemia cell line, the different concentrations of SNP and different time of culture were used to treat K562 cell. At the same time, potassium ferricyamide (PFC) was used as control, blank was designed in experiment. Cell apoptosis was analysed by cell morphology, DNA agarose gel electrophoresis, DNA content, and annexin-V/PI labeling method. The TdT-mediated dUTP nick end labeling (TUNEL) assay was used to quantify in situ cell apoptosis. Reactive oxygen species (ROS) in cells and mitochondrial transmembrane potential (DeltaPsim) were labeled by dihydrorhodamin 123, 2', 7'-dichlorodihydrofluorescein diacetate and rhodamin 123/PI. bcl-2, bax, bad, p53 gene proteins and mitochondrial membrane protein were analysed by flow cytometry. The results showed that the K562 cell apoptosis was confirmed by typical cell morphology, DNA fragment, sub-G(1) phase, TUNEL and annexin-V/PI labeling. A majority of K562 cells were arrested in G(0)/G(1) phase. During the process of SNP-induced apoptosis in K562 cell, the mean fluorescence intensity of ROS in cells was significantly higher than those in blank and PFC control, while the DeltaPsim reduced. The expression of p53, bax, bad, Fas protein and mitochondrial membrane protein increased and bcl-2 protein decreased after SNP treatment. It is concluded that SNP induces K562 cell apoptosis through increasing ROS in cells, expressing the p53, bax, bad, Fas protein and mitochondrial membrane protein and decreasing bcl-2 protein, opening the mitochondrial permeability transition pore and reducing DeltaPsim. Furthermore, the Fas was activated during the apoptosis process.

OBJECTIVEEpstein-Barr virus (EBV) is a common causative agent of infectious mononucleosis (IM) and capable of efficiently immortalizing primary B cells into continuously growing lymphoblastoid cells in vitro. As B cell activation antigen, CD23 expression is induced by EBV infection of B cells and remains constitutively expressed at high levels in virtually all EBV-immortalized cells, which have been strongly linked to the development of B-cell lymphoproliferative disease and lymphoma. Whereas previous studies were performed in vivo in animals or ex vivo cultures, the present study aimed to explore the role of EBV-immortalized cells (CD23(+)/CD19(+)) in vivo analysis of children with EBV-IM.

METHODSIn a prospective trial, a group of 30 patients with IM (18 boys and 12 girls) with mean age of 3.9 +/- 1.3 years (range 6 months to 8 years) were enrolled. Clinical diagnosis of IM was confirmed based on fever, lymphadenopathy, splenomegaly, lymphocytosis (> 50%), atypical lymphocytes (> 10%) in blood smears and the elevated levels of IgM antibody against EBV capsid antigen. The day of onset of fever was recognized as day 1 of illness. Blood samples taken during acute (3 - 5 days), early convalescent (about 11 - 15 days) and convalescent phase (about 30 - 45 days) were analyzed for expressions of CD19(+)/CD23(+), CD23, CD19 on peripheral blood mononuclear cells by flow cytometry (FCM) and was compared with those of control group.

RESULTS(1) The levels of CD23(+)/CD19(+) and CD23 expressions were markedly decreased in acute stage [CD23(+)/CD19(+) (2.22 +/- 1.47)%, (132 +/- 91)/mm(3); CD23 (3.12 +/- 1.88)%, (195 +/- 102)/mm(3)] and in early convalescent stage [CD23(+)/CD19(+) (4.51 +/- 2.25)%, (166 +/- 85)/mm(3); CD23 (5.55 +/- 2.76)%, (231 +/- 130)/mm(3)] in patients with IM as compared with those of the healthy controls [CD23(+)/CD19(+) (6.71 +/- 2.25)%, (215 +/- 68)/mm(3); CD23 (7.85 +/- 3.09)%, (249 +/- 86)/mm(3), respectively]. The earlier the history was, the lower the expressive levels were. The levels of CD23(+)/CD19(+) expressions returned to, but those of CD23 expressions exceeded, normal level in convalescent stage [CD23(+)/CD19(+) (6.72 +/- 2.16)%, (213 +/- 108)/mm(3); CD23 (9.46 +/- 2.73)%, (366 +/- 200)/mm(3)]. (2) There was a positive correlation in the expressions of CD23(+)/CD19(+) and CD23 among the three stages (P < 0.01). The positive correlation between the expressions of CD23(+)/CD19(+) and CD19 only occurred during acute stage (P < 0.01). There was no correlation between the expressions of CD23 and CD19 (P > 0.05).

CONCLUSIONEBV-immortalized cells and CD23(+) cells were inhibited effectively during the acute and early convalescent stage of IM. With the recovery of the disease, they gradually recovered and the levels of CD23 expressions exceeded normal level in convalescent stage.

OBJECTIVEInfectious mononucleosis (IM) is a lymphoproliferative disease caused primarily by the Epstein-Barr virus (EBV) infection. The initial viral infection by EBV occurs in B lymphocytes and is followed by an extensive proliferation of T lymphocytes. Previous studies on immunity to EBV (including IM) have mainly focused on activation of peripheral blood T cells, which are responsible for the lymphocytosis in blood during acute IM. B cells, regarding CD23 as their activation marker, are the target cells of EBV infection. There are few reports on their effect in patients with IM. The role of them during acute IM is not known yet. The present study aimed to explore the action of B cells in patients with IM.

METHODSIn a prospective trial, a group of subjects comprised 22 patients with IM (14 boys and 8 girls) with mean age of 3.48 +/- 0.81 years (range 7 months to 8 years). Clinical diagnosis of IM was confirmed based on fever, lymphadenopathy, splenomegaly, lymphocytosis (> 50%), atypical lymphocytes (> 10%) in blood smears and the elevated levels of IgM antibody against EBV capsid antigen. The day of onset of fever was recognized as day 1 of illness. Blood samples taken during acute (3 - 5 days) and convalescent phase (about 15 days) were analyzed for expressions of CD19, CD19(+)/CD23(+) on PBMC by flow cytometry (FCM) and was compared with those of control group. The number of the days with fever was recorded.

RESULTS(1) The levels of CD19 and CD19(+)/CD23(+) expressions were markedly decreased in acute stage [CD19 (5.63 +/- 2.91)%, (387 +/- 178)/mm(3), CD19(+)/CD23(+) (2.45 +/- 1.87)%, (160 +/- 99)/mm(3)] and in convalescent stage [CD19 (12.49 +/- 5.70)%, (428 +/- 156)/mm(3), CD19(+)/CD23(+) (5.05 +/- 2.79)%, (172 +/- 78)/mm(3)] in patients with IM as compared with those of the healthy controls [CD19 (16.20 +/- 2.80)%, (545 +/- 150)/mm(3); CD19(+)/CD23(+) (7.08 +/- 2.78)%, (249 +/- 136)/mm(3)]. The earlier the specimens were taken after onset, the lower the expressed levels were. (2) There was a positive correlation of the expressions of CD19 and CD19(+)/CD23(+) between acute and convalescent stage (P < 0.01);there was also a positive correlation between the expressions of CD19 and CD19(+)/CD23(+) during acute and convalescent stage (P < 0.01). (3) A negative correlation was found between the duration of fever and the level of CD19 and CD19(+)/CD23(+) in acute stage (P < 0.01).

CONCLUSIONThe results indicate that B cells and CD23(+) B cells were significantly inhibited during the onset of IM in the patients, that with the recovery of the disease, the condition was gradually improved, and that the more evidently the CD19 and CD19(+)/CD23(+) decreased, the more serious the clinical symptoms were and the longer time the recovery needed. The levels of CD19 and CD19(+)/CD23(+) expressions may be useful in diagnosis and predicting the severity.
